Properties of Common Metals

STEEL
One of the most common material used in welding. Steel is a strong, highly applicable material welders spend most of their time working with, if not exclusively. Commonly used in projects that require a sturdy, easy to work with, and best of all, a more affordable material. But steel does have it’s drawback by having to deal with it’s heavy weight, potential for rust, and needs to be cleaned regularly prior to welding.

STAINLESS STEEL
Unlike regular steel, stainless steel Is not only a remarkably strong, highly resistant to corrosion(rust), and improves hygiene by making it difficult becoming contaminated by bacteria. It is also highly applicable with the ability to be welded by most types of welding processes. Stainless steel is commonly used in projects in environments with high precipitation, like on the coastline.

ALUMINUM
Aluminum is unique in a few way from steel. For instance, is very lightweight compared to steel, making it easy to maneuver and work with on site. When welding aluminum, it is almost always going to be via Tig welding, because aluminum conducts heat exponentially greater than steel and has a very low melting point, processes like Mig and Stick will make it very difficult making a clean and consistent weld.
